Companion urns for couples are designed to hold the ashes of two people together — most often spouses or lifelong partners who wished to remain side by side. For families honoring a couple, choosing one shared vessel can be a deeply meaningful decision, a lasting symbol of a bond that outlived them both.
This guide explains everything about companion urns for couples: how single-compartment and double-compartment designs differ, the sizes and capacity you need, common materials and price ranges, and the practical questions to ask before buying. Whether you are pre-planning together or arranging for a couple after a loss, understanding your options helps you choose a vessel that fits both their remains and their story.
What Are Companion Urns for Couples?
A companion urn is simply a larger urn built to hold two full sets of cremated remains rather than one. There are two main designs, and the difference matters.
- Single-compartment companion urns hold both people's ashes together in one shared space, symbolizing unity. Ashes may mingle over time.
- Double-compartment companion urns have an internal divider or two separate openings, keeping each person's remains distinct while housed in one urn.
Some families choose the single design as a poignant statement of togetherness; others prefer a divided model so remains stay separate — for instance, if one partner may later be scattered or divided. Neither is "correct"; it is a personal choice. For background on standard vessels, see our cremation urns complete buying guide.
Sizing and Capacity: How Big Should a Companion Urn Be?
Urn capacity is measured in cubic inches, and the standard rule is one cubic inch per pound of healthy body weight before death.
A single adult typically needs about 200 cubic inches. Because a companion urn holds two people, it needs roughly double that.
| Urn type | Approx. capacity | Holds |
|---|---|---|
| Standard adult urn | 200 cubic inches | One adult |
| Companion urn | 380 – 450 cubic inches | Two adults |
| Oversized companion | 450 – 600 cubic inches | Two larger adults |
Always confirm the exact cubic-inch rating before buying, especially if either partner was above average in size. If you are unsure how much volume ashes actually take up, our guide on how much ash is left after cremation explains what to expect.

Materials, Styles, and Costs
Companion urns come in the same range of materials as single urns, just larger — which slightly raises the price.
- Metal (brass, bronze, aluminum): durable and classic; $150 – $500.
- Wood: warm and often handcrafted, suitable for home display; $150 – $600.
- Ceramic and marble: elegant and weighty; $200 – $700.
- Cultured stone or granite: ideal for outdoor or cemetery placement; $250 – $900.
- Biodegradable companion urns: for green burial or water release; $100 – $300.
Extras such as engraving of both names, dual birth and death dates, a shared quote, or matching keepsake urns for children add to the total. Because a companion urn is one vessel instead of two, it is often more economical than buying a pair.
Choosing the Right Companion Urn
Beyond size and budget, weigh where and how the urn will rest.
- Placement: Home display, cemetery niche, or burial each favor different materials and shapes. A columbarium niche may cap the urn's dimensions.
- Together or separate: Decide between a single shared chamber or a divided design early, as it changes the model entirely.
- Timing: If one partner dies years before the other, choose an urn you can open again later, or use temporary urns until both can be united.
- Engraving: Confirm the surface allows dual inscriptions and plan the layout in advance.
- Family wishes: Some relatives want small keepsake portions; you can pair a companion urn with tiny keepsakes so everyone has a piece.
If ashes may eventually be divided among family, our guide on dividing ashes among family members can help you plan portions before filling the urn.
Personalizing a Companion Urn
Because a companion urn holds two intertwined lives, personalization carries extra meaning. Options families choose include:
- Dual engraving of both names, birth and death dates, and a shared line such as "Together Always" or "Forever Side by Side."
- A joined motif — interlocking rings, two doves, a tree with two trunks, or a heart split and rejoined.
- Matching keepsakes so children or grandchildren can each keep a small portion while the couple stays united in the main urn.
- A shared quote or verse the couple loved, or a lyric from "their" song.
Plan the engraving layout before ordering, especially if the second person's dates will be added years later. Ask the seller whether the surface can be re-engraved after the first inscription, since not every material allows it. Thoughtful personalization turns a functional vessel into a lasting tribute to a partnership.
Where to Buy Companion Urns and Your Rights
You are never required to buy an urn from the funeral home handling the cremation. Under federal consumer protections, you may purchase a companion urn from any retailer — online specialists, artisans, or general merchants — and the funeral provider must accept it without charging a handling fee.
- Online urn retailers typically offer the widest selection and best prices, with clear cubic-inch ratings.
- Funeral homes are convenient but often marked up; compare before buying.
- Independent artisans can craft custom wood, ceramic, or metal companion urns, though lead times are longer.
Order early enough to allow for engraving and shipping if you want the urn ready for a memorial. If timing is tight, a temporary urn can hold ashes until the permanent companion urn arrives. When both partners' remains will eventually share the vessel, confirm the model reopens easily so the second set can be added later without damaging the urn. Our guide to keeping ashes at home covers placement and care once the urn is filled.

Frequently Asked Questions
What size urn do you need for a couple?
Companion urns for couples typically need 380 to 450 cubic inches — about double a standard 200-cubic-inch adult urn — because they hold two full sets of ashes. Choose an oversized model of 450 to 600 cubic inches if either partner was larger.
Do companion urns keep ashes separate?
It depends on the design. Single-compartment companion urns hold both sets of ashes together, while double-compartment models use an internal divider to keep each person's remains distinct. Decide which you prefer before buying.
Are companion urns cheaper than two separate urns?
Often, yes. Because a companion urn is a single vessel, it usually costs less than buying two individual adult urns of the same material, even though it is larger. Engraving both names may add a modest fee.
Can you add the second person's ashes to a companion urn later?
Yes, if you choose an urn that can be reopened. Many families use a companion urn when one partner dies and add the second set of ashes years later. Confirm the closure is removable rather than permanently sealed at purchase.
Can companion urns be buried or placed in a niche?
Yes. Companion urns can be kept at home, buried, or placed in a cemetery niche, though niches often have size limits. Confirm the maximum dimensions with the cemetery before selecting a larger companion urn.
